Definitions
- the invention relates to the use of a concentrated quenching water, called "corn steep", resulting from the starch industry, as a means of combating the fire risks caused by self-heating and the risks of dust explosion induced by particles and microparticles contained in flammable organic dust materials from the extractive industry and by the explosive gases released during the self-heating process, during storage, transport and / or handling.
- a concentrated quenching water called "corn steep”
- Materials from the extractive industry are, when they consist of flammable organic materials, cause fires by self-heating related to the characteristics of these materials and explosions related to organic dusts induced by said materials and release of explosive gas as a result of self-heating, during storage, transport and / or handling.
- the process in question adds compressed air, a solution of hydrochloric acid in the coal seam during the extraction, solution also heated preferably to several hundreds of degrees, then a steam injection, to remove the condensates.
- said method is for the purpose of elimination, in a heavy manner (high-viscosity solution acting bacterially with complementary injection of a solution of hydrochloric acid heated to several hundred degrees, and then of steam). methane contained in the coal during extraction, which has the effect of avoiding dust during extraction and washing.
- WO9100866 describes, more particularly, the effect of an aqueous chemical composition intended to suppress the generation of dust.
- the firing of a fire requires additional energy input in the form of minimum ignition energy to overcome the barrier of activation energy of the system.
- minimum ignition energy to overcome the barrier of activation energy of the system.
- To have a combustion it is also necessary to reach the minimum temperature at which the reaction with flame development will occur. This temperature is called the ignition temperature.
- the induction period is reduced when the temperature increases. It also depends on the pressure, the concentration of fuel, the type of material, therefore its reactivity and its contained additives. The larger the sample volume, the easier the heat buildup will be.
- the rate of oxidation of coals or cokes at room temperature is very low and plays an effective role in the self-heating phenomenon only for large heaps and after a very long time. This is the time needed to go from the storage temperature of coal or coke (ambient temperature) to a temperature of the order of 70-80 0 C beyond which the self-heating takes place.
- the oxidation rate increases as the grain size decreases. Indeed, when the particle size decreases, the specific surface of the grains increases and therefore also the surface capable of reacting with the oxygen of the air.
- the pyrite content is also a factor influencing the rate of oxidation.
- the presence of pyrite in the form of small particles well dispersed (large surface area) promotes self-heating while the presence of massive pyrite does not lead to a significant increase in the rate of heating.
- the explosion is a rapid combustion of a mixture of gas, coal dust or both, with air, in a confined or partially confined space, in which the heat released is more important than the heat lost in the environment .
- explosions are related to the presence of large quantities of dust formed during the handling or crushing of fuels. Explosions may also be due to pyrolysis or incomplete combustion gases (carbon monoxide) formed during the self-heating of coal deposition.
- the phenomenon of dilation is responsible for the pressure effects observed during an explosion in a confined or partially confined space.
- the pressure effects are much greater (maximum pressure of the order of 5 to 10 bars) and can lead to the destruction of the devices.
- the explosion is a special combustion using the following specific parameters:
- the dust must be in suspension to form a large surface of contact with the air;
- the atmosphere must be confined so that the pressure can increase.
- compositions containing vegetable proteins were carried out using compositions containing vegetable proteins with the objective of selecting those suitable, simultaneously:
- compositions tested were more particularly chosen from quenching water from the starch industry and more particularly those from corn kernels by a process which consists of adding sulfur dioxide ( SO 2 ) during the quenching step allowing the release of various constituent corn (minerals, amino acids, phosphate, potassium hydroxide, ...) to, after concentration, obtain a soaked water of concentrated so called "Corn Steep".
- SO 2 sulfur dioxide
- CEBTP-SOLEN located at the Millennium, 685 Rue Louis Lépine, 34000 opponents for a period extending from July to September 2008.
- the material that has been retained, particularly prone to contain dust and fire hazard by self-heating, is petroleum coke.
- composition which has been retained is the "Corn Steep", concentrated quenching water, marketed by the company ROQUETTE under the reference SOLULYS 048 E.
- N total 3.55%
- K 2 O soil 3.05%
- P 2 O 5
- composition is currently used as:
- binder for the manufacture, in particular by extrusion, of animal feed and nutritional substance
- a dosage rate, relative to the material to be treated of between 3 and 12%.
- the implementation of the tested composition on organic products such as coals or cokes can greatly reduce the risk of fire from self-heating through the wetting effect and sustainable agglomeration particles, increasing the size of the grains, reducing the fixing of condensation moisture and avoiding any increase in mass of the temperature which helps to avoid internal oxidation phenomena, and therefore stops any self-heating effect and explosion.
- composition also leads to a very significant reduction of environmental hazards, a reduction that may be followed by a reduction in the means of prevention and control, which is a source of financial savings, particularly with regard to:
- the vegetable composition tested is a product containing water-soluble vegetable proteins derived from cereal or proteinaceous fats and / or quenching water generated by the starch industry.
- This composition, wetting, natural, non-toxic and biodegradable liquid consistency can be diluted with water with ease of implementation can be used in different application techniques such as spraying, misting, atomization by means of adapted ramps.
- T.G.A.P. particulates General Tax on Polluting Activities
- the invention relates to the activities after extraction, namely: storage, transport and / or manipulation;
- the composition, object of the invention is not used during the extraction and is not used as a humidifier during washing: it is used after, during storage or handling and acts as a wetting agent, which gives it a lasting durability over several months, avoiding the self-heating of the organic material (coal or coke) and the dust particles due to its granulation effect due to the wetting character and not to the moisturizing character of the document GB 1492238 and not the oxidation or partial removal of methane.
- said document uses an aqueous composition with high viscosity comprising so-called chemical products and starch, while the composition object of the invention uses natural and organic products from the starch industry.
- the replacement of the composition used in the document GB 1492238 by that object of the invention can not have the same effects during the extraction and would have no effect since it can only act on materials already extracts with a more or less fine grain size, which is not the case with the materials to be extracted, which are in bulk as in the coal seams.

- the following table summarizes the monitoring data concerning the water content (W) and the apparent density (p) with the implementation of the tested composition diluted to 5% of pure product and dosed at 10% on the material. whose density was before treatment of 0.720 t / m 3 .
- the density remains substantially unchanged.
- the following graphs display, as a function of time, the particle size monitoring data, whose pass at 315 ⁇ m, before the implementation of the tested composition, amounted to 15% and that to 80 ⁇ m to 7.7 % (mixture diluted to 5% and dosed at 10%).
- Figure 1 gives, at different periods of time, the percentage of loops depending on the opening of the sieve in mm;
- Figure 2 gives the variation (in%), in time (in days), of the passer to 0.315 mm.
- the optimization study makes it possible to specify the evolution of the percentage of fines as a function of the water dilution rate of the tested composition and the determination of this diluted composition in the material to be treated.
- FIG. 3 is the graphical representation, at different dilution ratios (3, 5 and
- the dilution rate of 7% can significantly improve the results, passers to 7% of the mixture being of the order of 3% to 0 to 10.3% of mixture;
- the composition tested diluted between 5 and 7% of water acting as a wetting agent and a fixer by agglomerating the particles and microparticles, thereby avoiding this moisture fixation .
- diluted quenching water will be mixed with black soap (oil + alkaline solution) to increase the wetting properties of the composition.
